求救：和运营商的一号信令对接，但无法打出电话

和运营商对接了一个E1的一号信令线路，用的openr2，但是无法拨出电话，运营商的E1线路很正常，在别的E1接口上能够正常拨出电话。

请帮忙，谢谢！

错误信息如下：

怎么没见End of DNIS ： F的发送呢

MFC/R2 Chan 1: F on -> [2/DIALING /Group I /End of DNIS ]
MFC/R2 Chan 1: <- 3 on [2/DIALING /Group I /End of DNIS ]
MFC/R2 Chan 1: F off -> [2/DIALING /Group I /End of DNIS ]
MFC/R2 Chan 1: <- 3 off [2/DIALING /Group I /End of DNIS ]

openr2现在的配置里确实是有中国制式，但并不确定是否有效，没有得到过客户的反馈，最好让局方那边检查一下是否是送信令上有问题

有效地，接电话就没有问题

一号信令是不是分为：入和出，两种呢？交换机那边配成一号信令（出），这边asterisk就能收到来电。交换机配置一号信令（入），asterisk这边打过去就无法打出

请检查运营商那里，呼出和呼入的服务是否都已经打开。
